Behavior of gases check

Which container will have lower pressure?

• left
• right
• they both have the same pressure

Directly proportional means that as one value increases ....................

• the other stays the same 
• the other increases as well
• the other decereases
• the other goes to zero

At a constant pressure, if the temperature is increased, what happens to the volume?

• Increases

• decreases

• stays the same

Which of the following would increase the pressure on a system?

• Increase the Temperature
• Pump in more gas
• Decrease the volume
• All of these

What will happen to the volume of a gas if the pressure increases, with constant temperature ?

• Increase
• Decrease
• Nothing
• Explosion!

When a cold tire is inflated to a certain pressure and then is warmed up due to friction with the road, the pressure increases. This happens because the

• air molecules hit the walls of the tire less frequently
• rubber in the tires reacts with oxygen in the atmosphere
• air molecules speed up and collide with the tire walls more often
• air molecules diffuse rapidly through the walls of the tire.
